Combined type large-span deep foundation pit prestressed steel supporting system
The invention discloses a combined type large-span deep foundation pit prestressed steel supporting system. The steel supporting system involves a truss supporting system provided with at least two supporting beams, and an inhaul cable system is arranged at the bottom of the truss supporting system; the inhaul cable system comprises a plurality of V-shaped rods, the bottoms of the V-shaped rods are movably connected with a main inhaul cable through inhaul cable connectors, the two ends of the V-shaped rods are fixedly connected with two supporting beams on the outermost side of the truss supporting system through movable connectors separately, and the two ends of the main inhaul cable are hinged to two auxiliary inhaul cables through three-way lock heads separately; and the ends, away from the three-way lock heads, of the four auxiliary inhaul cables are movably connected with the bottoms of the two supporting beams on the outermost side of the truss supporting system correspondingly. According to the steel supporting system, the arranged inhaul cable system not only can solve the self-weight problem of the truss supporting system, but also can promote that no steel stand column or concrete stand column pile exists in a foundation pit, the earth excavation efficiency is greatly improved, the construction period is shortened, and the supporting system can be repeatedly used and has the characteristics of being short in construction period, low in cost, good in safety performance, environmentally friendly, free of pollution and the like.
本发明公开了一种组合式大跨度深基坑预应力钢支撑系统，包括设有至少二根支撑梁的桁架支撑系统，桁架支撑系统的底部设有拉索系统；拉索系统包括若干V形杆，V形杆的底部通过拉索接头与主拉索活动连接，V形杆的两端分别通过活动接头与桁架支撑系统最外侧的两个支撑梁固定连接，主拉索的两端分别通过三通锁头铰接两个副拉索，四个副拉索远离三通锁头的一端分别与桁架支撑系统最外侧的两个支撑梁底部活动连接；本系统设置的拉索系统不仅能够解决桁架支撑系统的自重问题，还能促使在基坑内实现无钢立柱和混凝土立柱桩，大大提高土方开挖效率，节省工期,本支撑系统可重复使用，具有工期短、成本低、安全性能好、环保无污染等特点。
